HVAC Start and Run Capacitor Explained and Replacement – …
Voltage. A capacitor will have a marked voltage indicating its acceptable peak voltage, not its operational voltage. Therefore, you can select a capacitor with a voltage rating at or above the original capacitor. If you''re using a 370 volt capacitor, a 370 or 440 volt one will work, though the 440 volt unit will actually last longer.
Everything You Need to Know About Under Cabinet Lighting
LEDs do not operate on AC line voltage, but rather low voltage DC, so they will require a power supply to convert the line voltage. Similar to 12V halogen puck lights, you''ll need to figure out a way to keep the power supply hidden in your cabinet somewhere, or deal with a "wall-wart" that plugs directly into the electrical outlet.
